True/False?
A life cycle in an insect is usually the period of time that begins with the egg and ends with the adult (capable of reproduction). Some insects take just a few days to complete a life cycle. Others make take many years.

True. Insects under go various changes in development called metamorphosis. Flies take a few days to develop into an adult and the cicada takes 17 years.

It sounds true to me. The life cycle is complete when an adult lays an egg, thereby starting the process over again.

True.
In biology studies with fruit flies, students can raise several generations of flies in just one experiment. Fruit fly life cycles are short. In fact, if you place adults in a culture and allow them to breed, their eggs will hatch and develop into reproducing adults in just two weeks. http://www.woodrow.org/teachers/bi/1994/life_cycle.html
This site says that termite queens can live 50 years (though that's news to me), and that a "splendor beetle larva" was found that was 47 years old. Not sure how they figured that one out. http://thelongestlistofthelongeststuffatthelongestdomainnameatlonglast.com/long328.html
It's certain that periodic cicadas live a long time, and even silverfish live several years.
This site also talks about certain beetle larvae living for 20 to 50 years. http://ufbir.ifas.ufl.edu/chap12.htm

I think false. It ends with the adult laying another egg.
That is the entire life cycle of an insect.
EGG - LARVA - MATURE LARVA - PUPA - ADULT - EGG
completes the cycle (circle of life)

Sounds true to me too!
